I understand that error "NL-Network-01" could be because of the socket timeout at the server as the server is overloaded. Are these calls which get "NL-Network-01" response included in the response times.

I could see that some of the calls in my test are reaching to 300 seconds in the test. Looks like these are included as the normal call at the worst does not take more than 10 seconds at the worst.
